1 Claim. (Cl. 248282) This invention relates to an adjustablewall-supported portable lamp.

It is an object of this invention to provide a lamp which is simple andgraceful in its lines, and easy to manipulate.

It is a further object of the invention to provide a lamp which is easyand inexpensive to manufacture but which, nevertheless, is easy toadjust both in a horizontal direction and vertically.

It is a further object to provide a device of the character described inwhich the lamp cord is concealed within the body of the frame, and whichwill have no loose cord in any adjusted position, and which will,nevertheless, at any time yield sufiicient cord for any adjustmentwithin its capacity.

It is a further object to provide a lamp in which .the lamp socket iscarried by cord moving in a tube having a curved portion, in which thecurvature of the tube is used to impose just sufiicient friction on thecord to sustain the socket in the various vertical positions and yetpermit the cord to be easily moved through the tube, for verticaladjustment.

The invention accordingly comprises the invention hereinafter describedand disclosed in the accompanying drawings, in which Fig. l is a sideelevation of a device embodying this invention in one position ofadjustment; Fig. 2 is a side perspective view with the component partsseparated from each other just sufficiently to show their relativerelation; Fig. 3 is a side elevation of the lamp frame, without thecord; Fig. 4 is an elevation of the base; Fig. 5 is a front elevation ofthe device in a slight modification, showing the limits to which thelamp may be extended on both sides.

The lamp comprises a base and two arms 11 and 12. The base 10 is adaptedto be attached to a wall by screws 13, the heads of which pass throughkey-hole openings 14 in the wall of the base 10, and then slip intorecesses 15, the sides of which slip behind the heads. A slot 16 is cutthrough the wall of the base from end to end, wide enough to permit thelamp cord 17 to be inserted into the base through it.

The body of the lamp comprises tubular arms 11 and 12. The inner arm 11has its inner end bent downwardly at 18 to fit within the upper end ofthe base 10, and to be supported thereby. The outer end 19 of arm 11 isbent upwardly to receive a downwardly bent end 20 of outer arm 12, asshown, which fits within it. The outer end 21 of outer arm 12 is bentdownwardly.

The lamp cord 17 has at one end the usual plug 22 and at the other end asocket 23, and it extends through the three members, as shown in Fig. 1.The curvature 2,50,92 Patented Aug. 30, 1950 of the bent ends of arms 11and 12 is such as to impart sufficient friction on the cord to supportthe socket 23, and such shade as may be attached to it, in any positionof vertical adjustment, and yet permit the cord to be moved through thearms '11 and 12 in either direction to adjust the position of the lamp.This may be easily done by gripping the cord just below the base andpushing it into or pulling it out of the base.

Any suitable form of shade may be used and any suitable cord may beemployed and the proper friction on the cord to support the lamp may behad by proper choice of the curvature of the bent ends of the arms 11and 12.

Because the base 10 is supported by slotted eyes it may be taken oil thewall at will, by simply pushing it up until the heads of the screwsregister with and pass through the openings. Thus, it may be removed,leaving only two screw heads on the wall, and it may be moved fromposition to position wherever similarly spaced screws are placed.

The arms '11 and 12 are vertical at their ends, which serve as pivotpoints so that the lamp, itself, will remain in any adjusted positionbut the intermediate portions of the arms may be horizontal, as shown inFigs. 1 and 3, or both, or one of them may be inclined, as shown in Fig.5.

If desired there may be provided a C shaped ring 24 surrounding the topof the base 10 with the slit in the C facing the wall, to prevent thespreading of the top of the base if the user should pull excessivelyhard upon the arms of the fixture.

A bushing 25 of plastic is preferably inserted in the end 21 to protectthe cord 17 as it is pulled out or in.

It will also be clear that the base may be used to support other formsof lamp frames, and permit them to be attached at any convenientlocation, at will.

What I claim:

A portable lamp frame comprising a base, a tubular arm having one endbent downwardly to pivotally engage said base and having its other endbent upwardl a second tubular arm having one end bent downwardly topivotally engage said upwardly bent end, and having its outer end bentdownwardly, said frame having an internal diameter to receive a lampcord extending through all three of said members, and to permit the cordto slide therein to adjust the lamp to said base comprising a tubularmember having a longitudinal slo-t therethrough through which the cordmay be removed laterally whereby the base may be completely detaohedfrom the lamp, said slot extending throughout the length of the base,said one end of said first mentioned arm being detachably fitted intosaid tubular member, and key-hole openings by which said tubular membercan be attached to a wall.
